DETAILED DESCRIPTION OF THE PREFERRED EMBODMENTS

The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

Referring to FIGS. 1 and 2, the constructive water resource recycling method according to the invention includes digging the underground soil layer 10 and burring pluralities of great-sized water reservoirs 50. Meanwhile, deep drainage trenches 40 are built in the underground soil layer 10 which is paved with a macadam stratum 11 and then an instantly permeable layer 12 composed of macadam, pebbles or sand. A rigid ground surface 13 formed by reinforcing steels and concrete is paved on the instantly permeable layer 12 to serve as walkways 20 or roadways 30, which are subsequently drilled by drilling equipment 70 (as shown in FIG. 4) to form pluralities of water permeable holes 31 such that the rain accumulated on the ground can be led down to the underground.

The great-sized water reservoirs 50 buried in the underground soil layer 10 are peripherally provided with connecting pipes 51 for communicating with one another. The top of each water reservoir 50 is provided with a drainpipe 52, which has a cover 21 at the outlet end, for connecting to the ground surface. An underground water reservoir room 53 can be provided at a certain position where the connecting pipes 51 combine, while the water reservoir room 53 is further connected with a water-drawing pipe 54 to reach the ground surface. The water accumulated underground can be drawn up to the ground surface via a water pump 62 of natural power, while the end of the branches of the water-drawing pipe 54 may be installed with a sprayer 63 for sprinkling purpose (as shown in FIG. 3). The water accumulated in the water reservoirs 50 can be drawn up to the ground surface with the time and amount fixed automatically for flowering the road trees and flowers, such that the gardening job in the city can be done more easily and automatically. Said natural power can be generated by a wind power generator 60 or a solar generator 61, thereby reaching an environmental effect.

The deep drainage trenches 41 provided under the macadam stratum 11 are deeper than general trenches and substantially have a close bottom. Water inlets 41 are provided on the side walls at the level as the bottom of the macadam stratum 11 for leading the permeated rain. A drainage band 42 may be paved adjacent to the bottom of the macadam stratum 11 such that the water can be led into the water inlets 41, and instantly drained away along the deep drainage trenches 40. Part of the rain retained in the soil can be led into the water reservoirs 50 via drainage band 46 for accumulation purpose. The water 55 accumulated in the water reservoirs 50 can be drawn out by a water pump 62 for utilization. Depending on the specific needs, trench bottoms 44 of permeable paving can be provided in the deep drainage trenches 40 at a certain distance, such that when the surplus rain in the deep drainage trenches 40 can be drained away through the permeable holes 45 on the trench bottoms 44 to the underground soil to supplement the underground water resource. The top of the deep drainage trenches 40 can be covered by trench covers 33 and drainage grilles 34 for instantly draining away the water accumulated on the ground.

As shown in FIGS. 4 and 5, the instantly permeable layer 12 composed of macadam, pebbles or sand is installed under the roadways 30, which is emphasized in the afore-mentioned embodiment as a rigid ground paving 13 constructed by reinforcing steels 36 and concrete. Alternatively, the roadways 30 can be paved with permeable asphalt 14 to soften the roadways 30, thus reducing the noise occurred by the moving vehicle. Besides, the roadways 30 can be drilled by drills 71 of drilling equipment 70 to form pluralities of permeable holes 31, thereby instantly drawing the rain accumulated on the ground into the underground.

Referring to FIGS. 1 to 3, permeable holes 22 are provided on the walkways 20, i.e. the rigid ground paving 13 is made with tile lines by way of paper moldboard or pattern technique, and is drilled with drilling equipment 70 to form pluralities of permeable holes 31 at the border of the tiles. Accordingly, the rain can instantly permeate into the instantly permeable layer 12 and the macadam stratum 11.

It is worth a mention that the permeable holes 31 provided on the ground can have the function of instantly leading the water down to the underground. Therefore, when it rains, part of the rain can be led into the underground soil to supplement the water content of the soil, and concomitantly avoid floods. In case of hot weather and drought, the humidity contained in the soil can instantly vaporized upward through the permeable holes 31 (as a chimney effect), to obtain an automatic conditioning in terms of the temperature and humidity of the air, i.e. heat exchange effect (such as breathe effect), thereby reducing the temperature of the ground, avoiding softening of the asphalt 14 due to high temperature, and preventing sagging and impermeability of the roadways due to the vehicle's constantly running over. Meanwhile, it is also available to prevent the tires of the vehicle from heat melting and wearing due to the high temperature of the roadways. Moreover, the instantly permeable layer 12 can automatically condition the temperature to avoid the city from occurring heat-island effect.

As shown in FIGS. 1 and 2, the constructive water resource recycling method according to the invention can alternatively be applied to instantly defrost the frozen roadways. While the roadways 30 and the walkways 20 are provided with permeable holes 31 and 22, respectively, the great-sized water reservoirs 50 are buried under the ground. In view of terrestrial heat, the water contained in the water reservoirs 50 certainly has a temperature higher than that of the ground surface. Therefore, when it snows, the walkways 20 and roadways 30 can make the snow thereon gradually melted; and when the snow stops, they would speed melting of the snow, thereby reducing occurrence of traffic accidents.

Referring to FIG. 6, in the construction of the underground water reservoirs 50, a drainpipe 52 is connected at the top of each water reservoir 50 to reach the ground surface. The end of the drainpipe 52 may be covered by a cover 21, so that when it is intended to utilize the water in the water reservoirs 50 for the purposes of flushing roadways or distinguishing, an underwater motor 56 can be put down into the water reservoir 50 for drawing water up to the ground. Alternatively, the water pump 62 on the ground can be additionally provided with pipes 57 for deep going to the water reservoir 50 to draw the accumulated water up via the underground motor 56.

Concluded above, the constructive water resource recycling method according to the invention relates to providing constructive permeable paving on the ground surface; constructing under the permeable paving an instantly permeable layer, the macadam stratum, and the water reservoirs, which are connected with pipelines. By way of water pumps of natural power, the water contained in the water reservoirs can be drawn up to the ground for secondary use. Besides, deep drainage trenches are selectively provided under the macadam stratum; the side walls of the deep drainage trenches have water inlets such that the rain can be led down to the soil via drainage bands. As such, limit water resource can be efficiently recycled for fully utilization. In view of the novelty and environmental concept embraced by the present invention, as well as the value applicable to the filed, the inventor claims the invention as specified in the following claims.

It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
